Elela: Hi there! I see you have lots of questions! 🙂
Amora is the whitest grade of moissanite you can get. You can buy it at betterthandiamond.com.
Forever Brilliant is an enhanced moissanite by Charles & Colvard (the largest and most trusted supplier of moissanite), since natural moissanite in large enough sizes for stones is incredibly rare and I don’t believe has ever been able to have been used.
You can get the Forever Brilliant (FB) from many places such as, MoissaniteCo.com, Joseph Schubach’s, David Klass, stores on Etsy that advertise it, moissanite.com, and even ebay. I bought my moissanite ring from MoissaniteCo and am very happy!
The double refraction of moissanite is one of the reasons that this stone is so unique. However, if you’re looking for a stone that acts like a dimaond, the enhanced (forever brilliant) stone or the amora stone will be your best bet. Just be aware, that moissanite is a gemstone in its own right, so it has its own personality. It picks up colors around it and can be “moody”. Sometimes the stone will look steely gray, green, yellow, but for most bees it’s usually bright white. Moissanite even tests positive as a diamond on traditional diamond testers that jewelers use!
As for cuts, they have just about every cut imaginable. I just saw their emerald cuts and they are amazing! The radiant cuts differ from radiant cut diamonds, but I feel that all the cuts could pass as a diamond as long as the size is believable to your financial situation. Any stone under 1 carat does not need to be enhanced, as they are pretty white already.
The newer batches of moissanite that exist today aren’t milky or cloudy. If you go to a jewelry store that has older stock, they may be more yellow or cloudy, so I would definitely go to a source that orders directly from Charles & Colvard (C&C) or has stones that you can look at in person and see if you like them.
Just so you know, there are fancy color moissanites too! They have different shades of green, pinks, canary yellows, bourbon, and if you’re lucky, blues! My FI and I had a canary put into my engagement ring and we love it! You can see the colored moissanites on moissaniteco.com as well as moissanite.com. David Klass and Schubach’s will order fancy colors for you and make something custom if you’d like. All these places have wonderful craftsmanship!
If you have any other questions, please let me know! 🙂
